摘要： 根据特殊的地质和水动力学特征,对常规物质平衡方程进行了改进。将烃类和油层下伏的底水视为油藏分系统，含油区外的水体视为水体分系统,建立适合薄层底水油藏的物质平衡方程; 应用常规的边水侵模型,通过生产动态资料线性化处理确定水体大小。同时建立了包括水体在内的三维底水油藏数值模型,并进行了数值模拟对比研究。两种不同方法预测的底水体大小基本一致,表明采用改进的物质平衡方程和常规边水侵模型,确定该类特殊底水油藏水体大小的方法是可行的,并具有简便、实用等特点。

Abstract: Based on the special geologic and hydrodynamic features, the conventional material balance equation is modified.The hydrocarbon and bottom water underlying oil zone are considered as oil reservoir system; water zone out of oil area as water system, by which the material balance equation for thin-layered bottom water reservoir is established.Then common edged-water influx model is used to calculate aquifer size of this type bottom-water reservoir.Also, in order to validate the reliability of this method, 3D reservoir numerical model for bottom water or aquifer is developed and the correlation study of numerical simulation is conducted.The result shows that the bottom water or aquifer size predicted by the two methods is similar to each other, indicating that the method given by this paper is simple, reliable and practicable for use.

Key words: bottom-water reservoir, material balance equation, water encroachment, numerical simulation
